London Underground's Tube map has been redesigned to help people with anxiety or claustrophobia.

The new map, which you can download from TfL's website, shows routes that people can take to avoid areas with large stretches of tunnels. On the map, parts of the lines and stations underground have been given a grey overlay to indicate they're underground.

More than half of the 270 stations on the Tube network are above ground, with the Victoria and Waterloo and City lines the only ones that are completely underground.

The new map, which has been welcomed by charities, was created following suggestions from customers with anxiety or claustrophobia conditions. It's part of TfL's aim to improve the travel experiences of customers using public transport in London.

"This new map is an excellent resource for those wishing to avoid journeys where there are tunnels; serving as a great pre-journey planning aid and increasing access to public transport," said Nicky Lidbetter, chief executive of Anxiety UK.

"I sincerely hope that the map will encourage those with claustrophobia and/or panic attacks who have previously avoided this form of public transport out of fear, to re-consider their use of the Tube."

Earlier this year, TfL launched its 'Please Offer Me a Seat' badge to help disabled customers and those with hidden conditions, illnesses and injuries find a seat on the Tube more easily.
